question: upgrade to HID bi-xenon light. Electrical guru welcome in

[rnln]

question to those who upgraded our 911 head light to bi-xenon.

I bought bi-xenon setup with single D2C bulb, 55w.
Lenses with flap/motor that will flap up when high beam switch on. Bulb is still on, with same current?

Problem with our car is that when high beam switched on, low beam is off. What I need is somehow to keep 12v to keep going to my bulbs all the time.

My buddy told me about the "bi-xenon hi/low controller relay" to do this function. I search and found most of these controller are for 9007 and 9004, non is for D2C. I am not sure what is the different internally, if there is any. Then I sit down and think what is in this controller? Is it simply combining low and high wire together and add couple diots so that current won't go back to the light switch in the dash?
